Supplier or fabricator decision guide
Metal supplier vs custom fabricator: which one should you call?
Call a metal supplier when the deliverable is raw stock. Call a custom fabricator when the deliverable is a part, subassembly, enclosure, guard, bracket, panel, tray, or production-ready component made from requirements.
Buyer intent
A simple decision rule
If you are buying metal as inventory, use a supplier. If you are buying a result that depends on geometry, holes, bends, welds, finish, or fit, use a fabricator.
Many real projects involve both material and process. In those cases, a fabricator can review material selection as part of the manufacturing scope rather than quoting the material in isolation.
What a fabricator needs from you
A custom fabricator is reviewing risk as well as price. The more clearly you describe the part, the fewer assumptions the shop needs to make about fit, appearance, tolerance, finish, delivery, and repeatability.
Comparison table
| Decision point | Call a metal supplier | Call a custom fabricator |
|---|---|---|
| You need | Raw sheet, plate, bar, tube, angle, or channel by grade and size. | A finished or semi-finished part made from files or requirements. |
| Questions are about | Stock availability, grade, size, price per unit, delivery, and cut-to-length options. | Geometry, laser cutting, forming, welding, tolerances, finish, hardware, and assembly. |
| Files needed | Usually none beyond purchase specs unless simple saw cutting is needed. | DXF, STEP, PDF, sketches, photos, and notes help the shop quote accurately. |
| Best outcome | Material arrives ready for your own processing path. | Parts arrive ready for fit-up, finish, installation, or the next production step. |
Safe takeaways
- Raw stock buying is a material transaction; fabrication buying is a manufacturing-scope conversation.
- Fabrication RFQs should include files, tolerances, finish, quantity, and downstream process requirements.
- FortiFab's strongest public fit is custom drawing-driven metal fabrication from its Langley shop.
